Audigy ZS to Infrasonic Quartet worth the upgrade? [SOLVED]

The SoundBlaster Audigy 2ZS is a relatively old PC sound card. 

Looking at the www.newegg.com site they still list the Infrasonic but it is "deactivated" suggesting it has been discontinued??

you'd be better off getting a soundcard that was designed for recording if you're looking for low latency native driver and quality recording converters.  check my website for some recommendations.

I've never heard of the Infrasonic Quartet - that's why it's not on my site.  I can't review it or recommend it if I have never had any expierence with it or helped people with them on the forum before. 

I would be concerned that this unit does not have low latency drivers.  if I were you I'd get something that is certain to have low latency drivers like the m-audio units.

all video cards can pose a conflict like that.  most likely what actually happened is that when you initially installed it, windows assigned it a shared IRQ with the video card.  this is usually a problem.  sometimes changing the PCI slot will change the IRQ in windows and solve the problem.

Ah I see.
Great, I'm getting some where with the latency.

Beagle,
To use the mixer just as a mixer do I connect one cable from the headphone jack to the sound card in or two cables left and right main out and plug into the left and right ins of the sound card?

I really thought the Multmix was as it is....just a mixer.

BTW thanks for the help so far guys.
I need the knowledge you guys have or else I may continue buying equipment which I don't need and only to give me more hassle.

Ok thanks guys will update when I grab some mono patch leads to go from the left and rigth main out into the left and right ins of the Infrasonic.

UPDATE:-
Plugged the main outs of the mixer in to the inputs of the sound card and it works.
It seems I only need to use one Main out into one input and pan to the left channel on the mixer then go from mono to stereo at the sound card.
But one problem when using the mixer.
I have noticed with or without guitar rig, I can hear the clean tone from the guitar coming out as well with the guitar sound selection from Guitar Rig whenever I use it.

Is there anyway around this while using the mixer?

EDIT:-
I think I my have found the issue from dabbling with the settings in the infrasonic mixer but haven't tested this yet.
When i set the channel to Instrument I get what seems to be high gain as I noticed the system noise suddenly appeared.
I could hear the change in the noise whenever I moved my mouse, moved a window around the screen and whenever the hard drive was accessed.
So I reduced the gain till the noise disappeared.
But then i went into Sonar where I have a session which has a Guitar Rig preset used and noticed I could hear my guitar really clearly even without the Guitar Rig patch loaded.
So when I opened up the patch I had a weak signal to guitar rig which made a clean/slightly overdriven tone.
So I set the channel back to line and increased the gain and it's back to normal.

So in theory if I set the external mixer input from GTR to LINE I should get the same results where I don't hear the clean tone of the guitar.

So it appears what seemed logical (to select Instrument/Guitar) is the wrong thing to do if you do not want to hear the actual sound of the guitar but the sound of the guitar through guitar rig.
Learn something new everyday.

Update from previous post:-
I change the Alesis Line in from Guitar to Line one and it has pretty much stopped the sound f the Guitar coming through unless I turn the gain on the Alesis right up.

Routing from Guitar:-
Guitar>Alesis Line 1>Alesis L Main out>Infrasonic 1/2 in>Infrasonic 1/2 Out>Sony Amplifier In>Sony Amplifier Out to Speakers,

I have not had a good look at the Infrasonic Mixer program but yes that maybe the issue.
What I would like to happens is absolutely no sound coming from the guitar but only sending a signal to Guitar rig.

Thanks for replying johnny V.

I have solved the issue.
Turned out to be a driver corruption in which all send buttons in the GUI did nothing.
Every send was fixed to on.

So RogerS was correct on this issue in part as indeed it was "configured" directly to pass through to the outputs via driver corruption.

Only figured this out by installing some newer drivers which still cause me and I found out a fair few others have IRQ conflicts.

I have even been asked to send my driver version to these people since Infrasonic have deleted it from their site.
